So apparently Mos Def is officially (at least we kind of figured this for a while, anyways) with G.O.O.D. Music. From this months XXL Magazine:
Just as Kanye returned to his roots to scoop up Common, he recently recruited his buddy Brooklyn rapper/singer/actor Mos Def into the GOOD Music fold. Long regarded as a formidable talent by underground devotees and mainstream fans alike, Mos appeared on â€œTwo Wordsâ€ (from Kanyeâ€™s 2005 The College Dropout) and â€œDrunk and Hot Girlsâ€ (from KWâ€™s 2007 Graduation). Since his 1999 solo debut, Black on Both Sides, Mos has increasingly been pushed â€” whether by generational choices or self-exile â€” to the fringes of indie, alternative hip hop. Maybe it will take Kanye to reign him in.
